fix(sidebar): search what the row shows, not just the part that fits

Each sidebar row shows a truncated title and a branch. The filter read
only the truncated title, so typing the branch you can see — or the part
of the path the row elided — matched nothing, and the list emptied out
on a query that is plainly on screen.

It now matches the full title and the branch as well as the label.
